a new and useful Improvement in Electrical Distributers, of which the following is a specification.

My invention relates4 to magnetos and other generators that are employed in con? nection with internal combustion engines to supply current for ignition and other purposes, and 'it relates particularly to means for distributing the ignition current to the engine cylinders.

The vobject of my invention is to provide a simple and effective distributer which shall be so constructed as to permit of ready assembling and disassembling of its parts for inspection, adjustment or repair.

My invention'is illustrated in the accompanying ldrawin Figure 1 of which is a vertical, sectiona a small generator embodying the same, and Fig. 2 is a view in end elevation of the said generator, a portion of the distributer being shown in section. f

The invent-ion is here shown as employed in connection with a small 'generator of current suitable for ignition or other purposes, and it is actuated by a pinion 1 that is mounted upon one end of the generator wheel 3 is a circular insulating shaft 2 and a gear wheel 3 that meshes'with the pinion 1. The gear wheel 3 is secured to One end of a short shaft 4 that is rotatably mounted, by means of suitable bill-bearings 5, in the frame 6 of the generator.

Secured upon the outer faceof the gear block 8 in which is embedded a conducting tube 9, the axis of which is inclined to the axis of gear wheel 3 and block 8, and the inner end of which is provided with an exposed extension 10 to form a central contact member upon the outer face of the block 8. The tube 9 serves as a receptacle and guide for a brush 11, a spring 12 for resiliently pressing the brush outwardly being interposed between the inner end of the brush and the bottom of a recess in the block S that constitutes an extension of the opening in the tube 9.

The parts just described are inclosed by a cover block 13, that is clamped or otherwise suitably secured to the end face of the genview through one end of' erator frame and is preferably composed of. molded insulating material, it being pro-Y vided with Van inclined or frusto-conical in.- ner face against which the outer end of brush 11 bears. are a plurality of conductors 'it that areprovided at their upper ends with receptacles 15 for plugs 16 and that extend downwardly from the top of the cover, said conductors terminating at their lower ends in `enlargements or feet 17 that have uniformly spaced, exposed and inclined contact faces formed flush with the inclined truste-conical inner face of the cover 13, the said contact faces Embedded in the cover 13 being interposed inthe path of the move-- l ment of the brush V11 so as to beengaged 1n Ysuccession therebyl duringv its revolution.

Another conductor 18, that is also embedded in the cover 13 and extends downwardly from a receptacle 1.9 for a plug 19, terminates at its lower end, opposite the central Contact member lO'carried by the block 8, in a tube 20 that serves as a receptacle and guide for a brush 21, the said brush being caused to res'iliently engage the contact 'member 10 by means of a helical compression spring 22 that is interposed between the inner end of the brush and the bottom end of the tube 20.

In the use of the device, the plug 19 is .connected to the source of supply of ignition current, and' the plugs 16areconnected in proper order to the engine cylinders.` The current is conducted from the plugv 419a through the parts- 18, 2() and 21 to the central contact member 10 upon theblock 8 and its revolution, successively engages and con- .from thence to the brush 11, which', during l ducts the current to the lower ends of the y conductors 14, thus distributing the current to the engine cylinders in the proper se,

wardly, but insuiciently, to require manual depression or special attention when it is de sired to again'apply the cover, as the inclined inner face of the cover is extended y suiliciently to engage the end face ofthe brush When it occupies its outermost position. Thus, the brush will slide upon the inclined inner surface of the cover and Will be pressed inwardly as the cover is applied to the machine and approaches its normal and iinal position. l

I claim as my invent-ion l. A distributer comprising a plurality of spaced terminal members, a revoluble brush, and a pressure spring for said brush, the engaging faces 'of the brush and of the terminal members being' inclined With respect to the axis of revolution of the brush and substantially normal to the force .eX-

erted by said pressure spring.

2. A distributer comprising a revoluble brush, and a plurality of spaced terminal members With Which the brush is adapted to engage, the brush and the faces of the terminal members that are engaged thereby beingl inclined With respect to the axis of revolution of the brush.

3. A distributer comprising a rotatable member, a brush carried by the said mem,- ber and inclined with respect to its .axis of rotation, a cover for the yrotatable member having an inclined inner face against Which the 'said brush bears but also extended 1aterally beyond thebrush, and a plurality of spaced terminal membersA carried by the cover also having inclined faces corresponding to the inclined face of the cover and adapted to be engaged by the brush.

4. A distributer comprisingr a rotatable member, a brush carried by the said member and inclined with respect to its axis of rotation, a cover for the rotatable member having an inclined inner faceagainst Which the said brush bears, and a plurality of spaced terminal members carried by the cover also having inclinedfaces corresponding' to the inclined face of the cover and adapted to be engaged by the brush.

In testimony whereof, I have hereunto subscribed my name this 4th day of Nov.
